Rescaling the Plot Screen
X (time) axis
To rescale the X (time) axis there are several possibilities:
•
Enter a time in the Plot Selection windows (available from the Plot screen
via the
Select
button [
F6
])
• Perform a rescale directly in the Plot screen by pressing the Direction
left/right keys. The right key will shorten the time range by the factor 2. The
left key will enlarge the range by the same factor. Press the keys several
times to set up the appropriate time frame.
The time range is indicated at the bottom of the Plot screen. This setting is
independent from the active signal.
Y (signal unit) axis
To rescale the Y (signal unit) axis there are several possibilities:
•
From the Plot Selection windows (available from the Plot screen via the
Select
button [
F6
]) choose a signal from either list box and press the
Setup
button [
F7
]. You can specify a Y range separately for each signal. This
setting can also be made for signals not being part of the Selected Signals
list box. Rescaling directly from the Plot screen will overwrite these
settings.
• Use the
Rescale
button [ F7 ] in the
Plot
screen to adjust the Y axis according
to the minimum and the maximum signal value within the set time range.
Using this function provides the optimum signal display. It refers only to
the active signal indicated at the top of the screen.
• Use the selection keys to change the scaling of the Y axis by a factor of 2
respectively 1/2.
